IMPROVBD APPARATUS'FOR EVAPOBATING LIQUIDS..

TO ALL WHOM IT MAY CONCERN: y

Be it known that I, J. P. DARE, ofrSalem, in the county of Columbiana, and State of Ohio, have-invented Y a new and improved Mode of Evaporating Liquids; and I do hereby declare that the following is a full and exact description of the same.

The nature of my invention consists in the application of a'close cover, of any desired form and material, fitted upon any evaporating-pan, tank, kettle, or other similar apparatus, so aste admit little no air to the surface of the liquid to be evaporated, except through heated chambers or pipes, arranged around or within the {ire-box, and near the doorot' the furnace, and' so as to discharge little or no vapor fromV thesurface of the liquid, except through an opening into an elevated flue or chimney, located at the extreme end of the furnace opposite the door; the object being, by a strong currentf dryheated air, to eifect a more rapid absorption and removal of vapor from `the surface of the liquid. And I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part-of this specification, in which- Figure 1 is a. perspective view ofi the cover, as placedupon an evaporating-pan, in connection with an airinlet and an elevated flue or outlet.

A represents the cover, and a a short sections of `the same,'hinged at b. C represents the chamberv or inlet for heated air; B, the furnace, and F the iiue or chimney.

Figure 2 is a perspective view of a furnace, with the airchumbers or inlets and the pan, in readiness for the cover.

G represents the pan, C one end of the air-receiving chamber, and E the other. Figure 3 is a perspective view of a furnace, with the air-receiving chamber in place, and ready for the pan. D represents the air-chamber, C its outer opening, and E its inner. Figure 4 is a perspective view of a section of the cover, a little raised, to allow an examination of the contents ofthe pan, the skimming, them removal or renewal ofthe same.

A represents the main part of the cover; a, the section or small hinged part. E represents the inner opening of the air-chamber, and C the outer. v

Figure 5 l is another perspective view of the air-chamber,l arranged below andat' the sides of the.ire-box. What I claim, therefore, as my invention, and desire to secure by Letters Patent, is- 1. The movable and close-fitting cover A, -when used upon the evaporating-pan, tank, or kettle G, in combination with the hot-air chambers C D E, and the elevated {iue or chimney F, as set forth'and described.

' 2. fThe hot-air chambers C D E, when-used in combination with the evaporating-pan G, and the close-tting cover A, in the manner and for the purposes set forth and described.
